Cleveland C43255 3-Flute PM+ HSS-E Square CC Special Profile Roughing End Mill 1.5 pneumatic accessory

Cleveland C43255 Roughing End Mill

This Cleveland C43255 roughing end mill is built for heavy material removal in milling operations. It suits machinists and fabricators who need aggressive stock removal on ferrous workpieces. The powdered metal construction with TiCN coating supports extended tool life in demanding production environments. It is a 3-flute square profile cutter designed for high-efficiency roughing passes.

Practical limits of the Weldon flat interface

The Weldon flat shank provides secure clamping in standard holders but requires a matching set-screw holder for proper engagement. This interface transmits high torque for roughing cuts yet cannot accommodate quick-change or collet-style tooling without an adapter. The 1.5 inch milling diameter and 6 inch length of cut define the maximum radial and axial engagement per pass. Rigidity decreases as the tool extends further from the holder.

Replaces worn roughers

This cutter replaces dull or damaged roughing end mills of the same diameter and shank configuration to restore material removal rates. The upgrade from a conventional finishing end mill is justified when the priority shifts to rapid stock removal over surface finish. The special profile geometry reduces cutting forces compared to generic roughers, making the change worthwhile for high-volume roughing cycles on compatible machines. The TiCN coating extends replacement intervals in abrasive materials.
